We could avoid a large increase in temperature if greenhouse emissions peaked by the year of ?

Greenhouse effect: warming up of the earth's surface due to the high immersion of man-made carbon dioxide in the atmosphere.The concentration of carbon dioxide works like a gas panel of greenhouse allowing short incoming wave of solar radiation to come in but preventing the long heat wave to re-radiate out.

Measure to avoid a large increase in temperature of greenhouse emission such as:

Reduce, Reuse and Recycle.Factories install smoke filters.The vehicle uses natural gas or batteries.Use less heat and air conditioning.Do not burn plastic and other trash in open.Plant seedlings and trees.Enforce strict law on environment protection.Make people aware of Environmental campaign.
